i just didn't know what happened on my phone after turning it on and it ask for it's PUK code, wherein I didn't change the settings of my phone meanind I didn't put any password on my sim card. How can I get it's PUK code? I know it is found in the sim card holder when you purchase the sim card but my card is almost 4 years and I can not find it's holder. Is there any possibilities to get my sim card working again because it is very important in my personal usage.
What do you mean T-mobile sim card? Could you clarify if your sim card is from Globe or T-mobile? If your using a Globe sim card, you need to visit the nearest Globe Store at your location, just bring a valid ID for the PUK retrieval. However, if your sim is provided by T-mobile, you need to contact them directly.
